PlatformIO

PlatformIO is an open-source ecosystem for embedded development that provides a cross-platform IDE, unified debugger, and library manager for microcontroller programming. It supports over 1,500 development boards and 50+ platforms, including Arduino, ESP32, Raspberry Pi, and ARM Cortex-M, streamlining the workflow for IoT, robotics, and embedded systems projects.

Also known as: Platform IO, PIO, PlatformIO IDE, PlatformIO Core

Why learn PlatformIO?

Developers should use PlatformIO when working on embedded systems or IoT projects that require multi-platform support, as it simplifies dependency management, debugging, and testing across different hardware. It's particularly valuable for teams needing consistent toolchains and automated builds, reducing setup time and compatibility issues compared to vendor-specific IDEs.
